Changes since OpenSSH 5.7
=========================
Security:
* Fix vulnerability in legacy certificate signing introduced in
OpenSSH-5.6 and found by Mateusz Kocielski.
Legacy certificates signed by OpenSSH 5.6 or 5.7 included data from
the stack in place of a random nonce field. The contents of the stack
do not appear to contain private data at this point, but this cannot
be stated with certainty for all platform, library and compiler
combinations. In particular, there exists a risk that some bytes from
the privileged CA key may be accidentally included.
A full advisory for this issue is available at:

Portable OpenSSH Bugfixes:
* Fix compilation failure when enableing SELinux support.
* Do not attempt to call SELinux functions when SELinux is disabled.
